I got an adjustable fuel pressure gauge, but am not going to hook it up until I get a fuel pressure gauge to hook to the schrader valve. No on in my area carries one apparently, so i journied out of town and found one they SAID was going to work. Well it didnt, the checking thing to hook to the valve was too big, so I'm going to return it and go back to square one. Where can I get one that simply hooks to the schrader valve? Anyone know a part number or can lead me in the right direction?
